Mooring and Anchoring

We are performing mooring and anchoring analysis in which the environmental forces, wind/wave and current are applied to the vessel and its mooring/anchoring lines.

The vessel can be either anchored at sea, moored at quay, connected to another vessel side by side or by stern.
Such analysis allows the determination of  line tensions, vessel motions and allowable environments.

Calculations methodology is adapted and varies in line with the problem and project requirements:

  • Static: The environment is constant, the vessel is not moving
  • Quasi dynamic: The environment is dynamic, the vessel is moving, the cable dynamic is not taken in account
  • Dynamic: Environment, vessel dynamic and cable dynamics are all dependant

Strength analysis is performed considering the Ultimate Limit State which concentrates on the maximum in terms of environment, tension and motions.
Fatigue analysis allows the determination of the mooring lines fatigue submitted to operational environments associated to a fatigue life cycle called Fatigue Limit State.
